Hello, quelqu'un pourrait m’expliquer ce bout de code? svp.
Ce code donne accès à une map google où sont positionnés des points bien précis.
<style type="text/css">
html, body { height: 100%; margin: 0; padding: 0; }
#map { height: 100%; }
</style>
</head>
<body>
<div id="map"></div>
<script type="text/javascript">
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 50.85034, lng: 4.35171},
zoom: 12
});
var jours = ["dimanche", "lundi", "mardi", "mercredi", "jeudi", "vendredi", "samedi"];
var locations = [];
$.getJSON("https:opendata.bruxelles.be/api/records/1.0/search/?dataset=bxl_food_trucks", function (results) {
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (var i =0; i < results.records.length; i++) {
if (results.records[i].fields.lundi != undefined) {
locations[i] = {
'name' : results.records[i].fields.lundi,
'lat' : results.records[i].fields.latitude_breedtegraad,
'lng' : results.records[i].fields.longitude_lengtegraad
};
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i].lat, locations[i].lng),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i].name );
infowindow.open(map, marker);
}
})(marker, i));
}
}
});
// Try HTML5 geolocation.
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
var image = 'image/truck.png';
marker = new google.maps.Marker({
position: new google.maps.LatLng(position.coords.latitude, position.coords.longitude),
map: map,
icon: image
});
}, function() {
handleLocationError(true, infoWindow, map.getCenter());
});
} else {
// Browser doesn't support Geolocation
handleLocationError(false, infoWindow, map.getCenter());
}
}
function handleLocationError(browserHasGeolocation, infoWindow, pos) {
infoWindow.setPosition(pos);
infoWindow.setContent(browserHasGeolocation ?
'Error: The Geolocation service failed.' :
'Error: Your browser doesn\'t support geolocation.');
}
